Agenda & Proceedings

  • Session Format and Agenda:
    • this will be virtual session over a phone conference setting, augmented by in-session chat and shared computer screen support

    2. Opening by the session chair - Ian Horrocks (~5 min.)

  • Topic: "OWL 2: Tools & Applications"
Abstract: This is the second of our two back-to-back sessions devoted to OWL 2. Our session chiar, Professor Ian Horrocks (co-chair of the W3C OWL 2 Working Group) has brought together an expert panel of OWL 2 researchers and developers to show us some of the state-of-the-art in OWL 2 tools and applications. Again, we will have about 30 minutes for open discussion after all the panel briefings. The panelists and their presentations will include:
Please refer also Professor IanHorrocks' two preceding session in the series:
* "Scalable Ontology-Based Information Systems" - ConferenceCall_2010_07_22
* "OWL 2: The Next Generation" - ConferenceCall_2010_07_29
  • The OWL API: a Java API for working with OWL 2 ontologies - [ slides ]
    • By: Matthew Horridge (University of Manchester)
    • Abstract: This talk will present the OWL API, which is a high level Application Programming Interface (API) for working with OWL 2 ontologies.

The OWL API is widely used in various prominent software projects. For example, it underpins various OWL editors and browsers such as Protege 4, The NeOn Toolkit, Swoop and OWL Sight. Moreover, many OWL 2 reasoners, such as FaCT++, HermiT, JCel, Pellet and Racer provide implementations of the OWL API reasoner interface. This talk will cover the main features and design philosophy behind the API, and will give some idea of how the API is used in applications.

  • The Protégé Tool Suite for Editing OWL Ontologies - [ slides ]
    • By: Timothy Redmond and Tania Tudorache (Stanford-BMIR)
    • Abstract: The Protégé group has developed a suite of tools for editing OWL 2 ontologies. Protégé 4 is the tool of choice for editors who want full OWL 2 support. Recent developments in Protégé 4 include client-server support allowing multiple users to access and edit an ontology simultaneously. Clients can choose to either access the ontology in an offline (svn/cvs) mode or in a live online mode where changes are seen as they occur. We will talk about the Protégé 4 database backend that allows the storage and fast querying of large ontologies. In addition we will present WebProtege, which is a powerful collaborative ontology editor that users access through their web browser. This version of WebProtégé provides support for collaborative discussion threads and includes full OWL 2 support.
    • Resources:
  • The NeOn Toolkit - [ slides ]
    • By: Andreas Harth (The NeOn Project; Institute AIFB; Karsruhe Institute of Technology)
    • Abstract: The NeOn Toolkit is a state-of-the-art, open source multi-platform ontology engineering environment, which provides comprehensive support for the ontology engineering life-cycle. The toolkit is based on the Eclipse platform, a leading development environment, and provides an extensive set of plug-ins (currently over 30 plug-ins are available) covering a variety of ontology engineering activities. Starting with version 2.3 the NeOn Toolkit is based on the OWL API and supports OWL2 features. The talk will cover basic NTK functionality and the set of OWL2 features that NTK supports.
    • Resources:
  • Pellet: OWL 2 Reasoner - [ slides ]
    • By: Evren Sirin (Clark & Parsia)
    • Abstract: This talk will introduce OWL 2 reasoner Pellet. Pellet is a sound and complete reasoner that supports all the features in OWL 2. In addition to the core reasoning services consistency checking, classification, and realization; it provides services for SPARQL query answering, explanation of entailments, and module extraction. This talk will briefly describe these features as well as the reasoning extensions to Pellet for closed-world data validation, qualitative spatial reasoning and probabilistic reasoning. Some examples of real-world applications using Pellet will also be described.

  • Application of OASIS Integrated Collaboration Object Model (ICOM) with Oracle Database 11g Semantic Technologies - [ slides ]
    • By: Eric Chan, Ramesh Vasudevan & Alan Wu (ICOM; Oracle); Deirdre Lee & LauraDragan (ICOM; DERI)
    • Abstract: OASIS Integrated Collaboration Object Model (ICOM), a proposed standard for integrated and interoperable enterprise collaboration, is an interesting application area for semantic database management tools in Oracle Database 11g Release 2. ICOM is a proposed standard ontology to integrate a complete range of collaboration activities for interoperable collaboration environments. It promotes seamless transitions among the collaboration activities to eliminate the fragmentation of collaboration tools. ICOM is defined from the outset for concomitant representations in Resource Description Framework (RDF) and Unified Modeling Language (UML), as well as in relational tables by some customized Object-Relational Mapping (ORM) schemes. Oracle Beehive collaboration service, which is a provider of ICOM, manages the ICOM-compatible data in Oracle Database to achieve high availability and scalability. By generating the ICOM RDF triples from the relational schema, Oracle database semantic technologies complement the ORM solutions to provide access to RDF/OWL and OO representations of the same dataset in RDBMS. Members of ICOM TC, Oracle Beehive Collaboration Technologies, and Oracle Database Semantic Technologies will jointly present the ICOM RDF modeling of the Ontolog forum data, including member profiles, discussion messages, wiki pages, conferences, etc., and demonstrate the Oracle Database support of OWL 2 RL, SPARQL, and SQL query interfaces for faceted search applications of ICOM RDF representations.

Peter P. Yim: now speaking - Mr. Matthew Horridge (U of Manchester) - "The OWL API: a Java API for

working with OWL 2 ontologies"

Frank Chum: Are the versions backward compatible?

Axel Polleres: What's the relation OWLAPI vs dig regarding the reasoning interface?

Peter P. Yim: (just for those who are unfamiliar with the process) we will hold Q&A until after all the

presentations are done. We should have time for discussion then, hopefully. Feel free to capture

your questions or remarks here, partly using this as a placeholder, and partly to document that for

the records

Peter P. Yim: now speaking - Dr. Tim Redmond & Dr. Tania Tudorache (Stanford-BMIR) - "The Protege Tool

Suite for Editing OWL Ontologies"

Nicolas Rouquette: It is often difficult to tell which ontology asserted a particular axiom and which

axioms a particular ontology asserts.

Nicolas Rouquette: The class browser view in particular shows all classes across all loaded

ontologies -- although we can show the ontology-specific prefix to tell which ontology declares a

particular class, it is sometimes difficult to get a sense of all the classes declared in a

particular ontology.

Peter P. Yim: now speaking - Dr. Andreas Harth (The NeOn Project; Institute AIFB, Karlsruhe Institute of

Technology) - "The NeOn Toolkit"

Peter P. Yim: now speaking - Dr. Evren Sirin (Clark & Parsia) - "Pellet: OWL 2 Reasoner"

Axel Polleres: afraid I need to run, thanks for the interesting talks!

Peter P. Yim: thank you for your participation - the entire proceedings will be available on our

archives - slides, audio recording, chat transcript, and all (just come back to the session page in

a day or two)

Ravi Sharma: @Evren - Pronto, does it break the distribution into histograms and for each histogram

you get the same reasoned answer i.e. is it equivalent to making it deterministic within the

histogram for a given axiom (or / Assertion)?

Ravi Sharma: @Evren - how does Pronto discover inferences that are probabilistic does it apply the

above process in previous question in reverse to fill a particular histogram with population /

samples?

Evren Sirin: Pronto uses lexicographic entailment algorithms to perform default probabilistic

reasoning

Evren Sirin: The semantics is based on first order probabilistic logic

Evren Sirin: The computation of probabilistic inferences has several steps and involves solving

linear equations among others

Enrico Franconi: @Evren, which is the reference for the integrity constraint validator? Is it just

what we can find on the web page?

Evren Sirin: @Enrico, longer technical report has several corrections:
